Tomas Volf 56809537a4 [rubygems/rubygems] Clean up temporary directory after generate_index --update
While generate_index did clean up temporary directory, when running with
--update flag, that did not happen and the temporary directory was left
behind.

This commit fixes that and modifies tests in order to make sure this is
not reintroduced later on.

Fixes #5635.
