When providing only the new directory path (i.e. without new filename) while
moving a file to a new directory with `spacemacs/rename-current-buffer-file`,
currently Spacemacs opens the file in a new buffer with the directory name.
Additionally, the `file-renamed-p` gets set the wrong value. To fix both
issues (with minimal work), it is easiest to just fix the `new-name`
value (alternatively fixing the `rename-buffer` and `set-visited-file-name`
forms later would not fix the wrong `file-renamed-p` value issue).
Finally when called with a universal-argument, then that argument
unintentionally gets 'passed' in the interactive call to
projectile-invalidate-cache. So this PR fixes that by changing the interactive
call to a funcall.
