When renaming a stash, if a colon (:) is present, it and everything preceding it is removed

Can initial create a stash with a colon (:) in the name without issue, but when renaming a stash the colon and everything preceding it is removed.  If multiple colons are present, only the first and it's preceding text are removed.

1. Create a stash with a colon, ie 'Test stash: Testing'
2. Rename the stash 'Test stash: Testing Testing' and save
3. Stash will be saved as 'Testing Testing'
