[Fixes #5587] Set permissions for current user when DEFAULT_ANONYMOUS…

[t-book]

This is a tiny but annoying problem. When we set DEFAULT_ANONYMOUS_VIEW_PERMISSION to False and some user does not add himself to the view select the layer will be broken. This small fix

• adds the current user in case DEFAULT_ANONYMOUS_VIEW_PERMISSION is False
• we're on the layer or document upload page.

• Confirm you have read the contribution guidelines

• You have sent a Contribution Licence Agreement (CLA) as necessary (not required for small changes, e.g., fixing typos in documentation)

• Make sure the first PR targets the master branch, eventual backports will be managed later. This can be ignored if the PR is fixing an issue that only happens in a specific branch, but not in newer ones.

• There is a ticket in https://github.com/GeoNode/geonode/issues describing the issue/improvement/feature (a notable exemptions is, changes not visible to end users)

• The issue connected to the PR must have Labels and Milestone assigned

• PR for bug fixes and small new features are presented as a single commit

• Commit message must be in the form "[Fixes #<issue_number>] Title of the Issue"

• New unit tests have been added covering the changes, unless there are explanation on why the tests are not necessary/implemented

• This PR passes all existing unit tests (test results will be reported by travis-ci after opening this PR)

• This PR passes the QA checks: flake8 geonode

• Commits changing the settings, UI, existing user workflows, or adding new functionality, need to include documentation updates

The backport to 2.10.x failed:

The process 'git' failed with exit code 128

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add .worktrees/backport-2.10.x 2.10.x
# Navigate to the new working tree
cd .worktrees/backport-2.10.x
# Create a new branch
git switch --create backport-5588-to-2.10.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick 8550d305aa9f36861e43a3b663437e0131e998cd
# Push it to GitHub
git push --set-upstream origin backport-5588-to-2.10.x
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-2.10.x

Then, create a pull request where the base branch is 2.10.x and the compare/head branch is backport-5588-to-2.10.x.
