Message:

Upgrade/Install: During the install process, add additional checking for exising tables.

This commit brings the changes in [49452] to the 5.4 branch.

If reinstalling WordPress, there is a condition where tables would exist in the database. Ensures that when that is the case, the install process can carry along without issue.

Fixes #51676.
