Remove applied tags on the tag selection

[Panquesito7]

Problem

When applying a tag in a package, you can still select applied tags to it. For example, my package has the Transport tag, but I can still see it on the list of remaining tags.

I believe this should be fixed to make things easier for package managers.

Solutions

Remove applied tags on the tag list when modifying a package.

Alternatives

Not sure what else we could do. Probably the current option?
