When a finished job's _process.h5 becomes the active run (or the user switches runs), the settings
panel shows the run's cell and space group but no longer ticks "Known unit cell", so the next run
determines the crystal from the data as a bare rugnux does, unless the user ticks it. Before, the
run's crystal - P1 for a run that ended there - was used by every later run until cleared.
