Bug fixes

This is a small change with no associated Issue.

• Fix bug where installing a suite.rc workflow that had been cylc validated in its source dir would result in a flow.cylc symlink being copied over still pointing to the source dir suite.rc instead of the one in the run dir

• Fix bug where the deprecated flow.cylc config item

  [scheduling]
      [[dependencies]]
          graph = foo

  (skipped [[[<recurrence>]]] section) did not log a warning when upgraded to

  [scheduling]
      [[graph]]
          graph = foo  # (same as R1 = foo)

• Do not show traceback when any CylcError gets raised during running of the workflow, only show traceback for generic uncaught exceptions (unless using --debug, in which case show traceback for all exceptions)

Requirements check-list

• I have read CONTRIBUTING.md and added my name as a Code Contributor.
• Contains logically grouped changes (else tidy your branch by rebase).
• Does not contain off-topic changes (use other PRs for other changes).
• Appropriate tests are included (unit and/or functional).
• Appropriate change log entry included.
• No documentation update required.
• No dependency changes.

Fast test failures seem to be due to pytest-dev/pytest-asyncio#209, passing locally for me on pytest-asyncio 0.14.0

passing locally for me on pytest-asyncio 0.14.0

Passing locally for me on pytest-asyncio 0.15.0 but failing on GH actions?!

I've pinned us back to 0.14.0 on #4176 until a fix is out

If you can get failures on 0.14.0 could you try out their candidate fix (on pytest-asyncio:master).
