`PaqSync` doesn't re-install plugins when `branch` is changed

[henriquehbr]

Bug

Change the branch of one plugin, run :PaqSync and the plugin stays the same

Workaround

Comment the plugin (with the branch property), run :PaqSync in order to uninstall it, then uncomment and run :PaqSync again in order for the plugin to be installed from the correct branch

Hi, I saw this issue and thought this would be an easy fix, but I'm currently deep in the shit that is git branches when the repository is cloned with submodules in mind. I think I can create a PR to fix this, but it will take a bit of time. I hope the maintainer accepts the PR :) Also, it would be kinda hard to know what the default branch is when you're switching back from specifying a branch to not doing it and wanting to go back to the default branch. Is it master? Is it main? Git doesn't know 👍🏻
