When tag wiki excerpt does not exist, but tag wiki does, some messages/activities are misleading

Question

The situation happens when there is an approved tag wiki, but no approved tag excerpt.

Here you can see it on the tag packaging:

It seems the message "tag has no wiki summary" is subordinated at the tag wiki excerpt existence.

Also, when clicking the "learn more button" the following message appears:

There is no tag wiki for this tag … yet!...

This is not true either.

Proposal.

1. When there is not a tag wiki excerpt, replace "tag has no wiki summary" for "tag has no wiki excerpt".
2. Whenever the tag wiki exists (the detailed one), enable the "learn more" button to direct the page to the tag wiki content.
