Fix (and rewrite) dx init/dx new (#2822)

* fix(cli)!: init subcommand now works correctly
* test(cli): added tests for init subcommands
* chore: moved `init` subcommand tests to its own file
* removed unnecessary arguments from tested command
* refactor(cli)!: new subcommand now behaves like cargo
* moved the hidden cursor workaround into a function
* feat(cli): added `branch` flag for init/new subcommands
* feat(cli): added `revision` and `tag` options
