Report the real wire count, and show current data

The summary line exists so that an empty wiring list is distinguishable
from one where every conductor was excluded, and it was reporting the wrong
number to do it. QSqlQueryModel fetches lazily, so rowCount() straight after
setQuery() returns the rows fetched so far -- 256 -- not the size of the
query. Measured with Qt's own QSQLITE driver: a 1000-row view reports 256
until the model is drained, then 1000. The test project quoted in slice 2
has 280 conductors, so this was already displaying 256 on our own data,
plausibly enough that nobody looked twice.

Drain the model before reading the count.

Also refresh the database before building the model. The dialog queries the
database rather than the diagrams, so anything not yet written through was
invisible here; with conductor text now updated on change that gap is
smaller, but a project loaded before this dialog was ever opened still
relies on the repopulate.
