Improve project renaming, deletion
Project names are not linked directly to project's repository path If the path is indeed changed (advanced section of the project's settings) then the storage path of the repository is to be affected.
This patch introduce a new method to handle the move of the hg repository linked to the project and how they are called alongside the git rename calls
The second commit includes a change to fix the delete of the .hg and .hg.wiki folders in case of a request for deletion.
Pending further checks and replication of the issue.
