Before this commit, when we moved from one line to the next, we did not
wait for the unselectRow to end. This means that if the read (from the
unselect row) completes after the default_get, the list renderer was not
in a coherent state (currentRow was set to null), which could (and did)
cause a crash.
This was found by pressing the TAB key a few times, and editing some
values.
Also, we slightly improved the logging in the mock server. Before this,
the responses from the mock server did not show from which route it came
from. But in this test, we specifically make sure that the rpcs
complete in a different order, so it was not really optimal.
