Fix broken link in `nf-core modules info`

[mirpedrol]

Close #1736

Don't add the prefix https://github.com to the link created by nf-core modules info. Make the link clickable if self.remote_location starts by 'http'

The command was also failing when there wasn't any module installed from a remote repository. I added the attribute self.local to ensure that we only try to obtain information from a local module if it is locally installed.

Hi @mirpedrol,

It looks like this pull-request is has been made against the mirpedrol/tools master branch. The master branch on nf-core repositories should always contain code from the latest release. Because of this, PRs to master are only allowed if they come from the mirpedrol/tools dev branch.

You do not need to close this PR, you can change the target branch to dev by clicking the "Edit" button at the top of this page. Note that even after this, the test will continue to show as failing until you push a new commit.

Thanks again for your contribution!
