Show warning message in TID manager when OIDs cannot be found

Fix #925

Code looks good but I wonder if a message box would be nicer. This Warning Bar for me looks like an error and not like an information that it does not make sense to use this dialog. Maybe just grayed out everything makes sense as well.

I'll try with a message box to let the user know why the dialog is grayed out.

@signedav, BTW, yesterday I think I finally did it with a message bar because I saw we had this message for a similar case in the Dataset Manager (i.e., empty project, probably first time opening Model Baker dialogs):

Should we bring a message box also for this Dataset Manager or we leave it as is and implement a message box for the OID Manager anyways?

Hm... Looks cleaner when we only have one row. So less strong opinion meanwhile. What is your opinion? Both box or both bar?

I'd prefer both with message bars, although I agree, it looks a bit overwhelming when we have more than one line. Perhaps we can rephrase it to make it fit into one line. The "Warning:" title could also be dropped to save space.

Another attempt (not sure it that will fit, apparently I have my verbose mode activated):
To use the OID Manager, first configure a connection to an Interlis database in the Import/Export Wizard.

If you have a shorter alternative, please let me know.

To use the OID Manager, configure a connection to an INTERLIS based database.

Thanks, screenshot updated and changes applied.
