431157: Accept gerrit URLs which include hash character

This allows copy-paste of gerrit review URLs from the browser to the
task repository manager, even if the URL points to a specific review,
filter, dashboard, or similar.

This change introduces a restricted access warning for calling
TaskRepositoryManager.stripSlashes(). This was done on purpose, as the
super implementation of getRepositoryUrl also cleans up using
stripSlashes.
