ResourcePackManager: Fix crash when removing pack

Avoid accessing destroyed `QTableWidgetItem` by retrieving the desired
path from the item before it's destroyed.

In `ResourcePackManager::Remove` pointers to the selected items in `m_table_widget`
were saved in the local variable `items` before calling `Uninstall`.
`Uninstall` called `RepopulateTable` which called
`m_table_widget->clear()`, destroying the table's descendants.  Upon
returning to `Remove` `items` then pointed to some of those destroyed descendants, and
passing `items[0]` to `GetResourcePackIndex` resulted in a call to
`item->row()` which was a use-after-free.
