Downgrade informational messages from warning level

[hgohel]

Fixes 13464

In upgrade scenarios informational messages that indicate old config files are being imported into the new config are now being treated as informational rather than warnings which may alarm the reader.

I both like and dislike this change.

Informational is probably more accurate than warning. However, both are inconspicuous to a user unless launching from the console.

Config imports are an exceedingly rare occurrence with more than enough time between to forget the implications. Perhaps a more prominent (and explicit and, perhaps, modal) dialog should appear? (With hotlink to a wiki article.)

I'd like to have the dialog state which config file(s) are being imported. As an example, if I flushed the 5.2 gramps.ini (perhaps due to windows appearing off-screen) then I would want to know that a 5.1 gramps.ini is being imported. That could undermine my objective.

Likewise, it is important information if my User Directory isn't in the default 5.2 path due to the existence of a legacy 5.1 User Directory.

Thanks for reviewing the PR. This change does not remove the message from being shown in the console so whatever the reader did previously, they can continue to do that after this change, without being alarmed :)

If there is a desire to make the messages more conspicuous, a new feature request would be best to handle that.

Agreed about a feature request. Just wanted to see if there is a consensus first.
