Shorten home folder path for info messages

[noxhirsch]

The info messages for opening files always show the full path. By using filemanagerutil.abbreviate, the info messages now show the shortened home folder path (only if the setting "shorten home folder" is enabled).

(In my own patch, I use:

-        text = T(_("Opening file '%1'."), BD.filepath(file)),
+        text = T(_("Opening from  %1\n\n%2\n\n"), BD.dirpath(file:gsub(".*/(.+/).*", "%1")), BD.filename(file:gsub(".*/(.*)", "%1"))),

which makes focusing on the filename a little bit easier.)

I assume that this can't really have anything to do with it, as I only changed the info messages themselves. Are you using the nightly version of KOReader from yesterday / today and before that it worked?

Could be related to #11774?

[Frenzie]

Like if you saved it as /some/path/ and now it only returns /some/path it'll never match, or something along those general lines.

Maybe.
I am not sure exactly when it happen (maybe I just notice that today) but I am sure a few week ago it work correctly as I use that couple week ago.
