Fix for bug #20480 (https://gna.org/bugs/?20480).

This was reported by Stanislava Panova (https://gna.org/users/stacy).

The problem was that the state file was saved after a RelaxError occurred during the model-free
analysis. The GUI data store information states that the active data pipe is called 'final'. But
an error occurred prior to the 'final' data pipe being created. The fix was to allow the state to
be loaded even if the GUI data store information has been corrupted.

Removed a debugging line from the State.test_bug_20480 GUI test.

Fix for the failed loading of states in the GUI.

This problem was caught by the State.test_bug_20480 GUI test. If the loading of a state file fails,
sometimes the relax data store can contain partial information from that file. Now if the loading
fails in the GUI, relax is reset.

Created the State.test_bug_20480 system test to catch bug #20480 (https://gna.org/bugs/?20480).

This bug was reported by Stanislava Panova (https://gna.org/users/stacy). The file
test_suite/shared_data/saved_states/bug_20480.bz2 is the same as that attached to the bug report but
with all residues except for 9 and 10 deleted.

Currently the bug is not triggered!
