Tails Installer workarounds for UDisks 2 bugs are not robust enough
As #9691 (closed) explains, due to bugs in UDisks 2 we had to add workarounds to Tails Installer. However, as seen e.g. on #10720 (closed) and #10987 (closed), our workarounds are fragile, to the point that we had to disable all automated tests that use Tails Installer, on Jenkins.
I suspect that the same technique(s) can be used to fix all these problems, hence this ticket to track them.
