Close Pull dialog (and similar) before opening progress dialog

When a pull fails (e.g. due to uncommitted local changes), the progress dialog shows the error.

Closing this dialog returns me to the initial pull options dialog. Selecting the default ("OK") option in this dialog retries the failed pull, which is almost always useless.

It is natural behaviour to select the default option to close the dialog when an error occurs, and multiple users here have confirmed that they regularly accidentally start a second pull attempt because of this.

Best suggestion is to have the initial pull options dialog close before the progress dialog opens. That way when there's an error, there is only a single dialog to dismiss and confusion is avoided.
