Add failed test first for removing broken symlink
Check path is symlink or not before removing

Current version of Path::Tiny cannot remove broken
symbolic link due to file test before unlink.
'-e' checks the existence of the resolved file for symbolic link,
so broken symbolic link cannot be reached to unlink statement.
