Remove Tika dependency for uploadvalidator

Tika was originally used over the MimeUtils2 library
because it was claimed that project.config was detected
as application/octet-stream. While project.config is in
fact detected as text/x-ini, other .config files are
detected as application/octet-stream.

Since I35920f66a makes all .config files detected as text/x-ini,
we can remove the dependency on Tika introduced in Ia2529f187.
