Ensure swapping doesn't get confused by apks in different repos.

Browse Source 
While investigating #1086 which was about swap being busted, I
discovered that we recently introduced a worse bug when working with
multi sig stuff. The swap process, when installing an app (or even when
listening for if a user started installing - before they even did
anything), would ask for an apk from any repo. This is wrong, because we
should only ask for the apks from the swap repo when presented with a
swap dialog.

By fixing this so that it asks for a specific apk, this may also
fix the issue in #1086, because that was about us not asking for enough
info from the database for each Apk which was returned. Now we just
return all columns, because the performance overhead should be minimal,
but it prevents this class of bugs, where we didn't fully populate
our value object. However, I'm not confident that it is fixed, because I
was unable to reproduce it due to the other crash fixed in this change.

Relevant crash:

```
