Do not allow empty tag names
It was allowed to use empty strings like "" or " " for a tag name.
After merging this PR, it will not be allowed anymore.
If there are some empty names in the database, they are not renamed.
A migration to rename empty names was not added because there can be more than one tag, for example:
We could have generated names like "no tag 1", "no tag 2", but it's not likely that admins have created empty tags.
Do not allow duplicate tag names
It was allowed to use empty strings like "" or " " for a tag name. And It was also allowed to have duplicate tags.
After merging this PR, it will not be allowed anymore.
If there are duplicate tag names, the duplication is removed by appending the tag id as a suffix to the tag name.
