Enabled recreation of test directory in apply_common_fixes function

Without it any test comprized of more than one cycle of installing-uninstalling
of ipa would fail due to the fact that test folder on the remote machine gets
deleted during ipa uninstallation.

Also removed duplicate call of apply_common fixes and added unapply_fixes to
uninstall_replica
