Paq doesn't reinstall a plugin when remote is changed

[nabaco]

Describe the bug
When switching a plugin from one git remote to another git remote, Paq doesn't recognize that and doesn't upgrade the plugin.

To Reproduce

1. Install a package: e.g. 'glepnir/lspsaga.nvim'; && PaqInstall
2. Change the package source: e.g. 'tami5/lspsaga.nvim';
3. Run PaqSync

Expected behavior
It is expected that Paq will recognize that the package source change, and re-install it. Either by manually changing the git-remote and doing git-pull, or (to be on the safe side) by deleting the original package and installing the new one.
