fix: correct "Remove from *arr" button (#1544)

This PR fixes the "Delete from *arr" button in the request list. It checks from the API whether the
*arr server corresponding to the request still exists before displaying the remove button, and fixes
a cache removal issue that could cause problems when deleting recently added media. This PR also
reverts #1476, which introduced problems during removal.
