Fix another issue with station details not being saved

Due to  what appears to be  a Qt bug, any  in progress user edit  to a
table  fields is  not  updated  in the  underlying  data models  until
QDialog::accept() is  called, this means that  model validation before
calling QDialog::accept() is tricky.
