table 'devel_debug_log' already exists.

Just had an idea ... :)

I personally cannot reproduce the problem by the means that were described in the summary.
What I did:

1. Run drush cex with Devel Debug Log enabled
2. Uninstall Devel Debug Log
3. Run drush cim

Result: The module was reinstalled perfectly fine.

When taking a look into my database overview (in this case PHPMyAdmin) I can also see that the table is automatically dropped just fine when uninstalling the module, even without our uninstall hook.
So I am not sure that the proposed resolution is actually the one to the problem that @killdery coelho is experiencing.

This means the MR fix would not be needed. So I think this is an indiviual issue in the authors page. So let's close this cannot reproduce.

Thanks @lrwebks!
