3D Beacons results in structure chooser don't include models if one of the selected sequences does not have a uniprot accession

An example:

1) Open Jalview, load the uniref50.fa file.
2) Right click on FER1_SPIOL and select 3D Structure Data...
3) 3D-Beacons search finds four models.

1) Open Jalview, load the uniref50.fa file.
2) Select all sequences, right click and select 3D Structure Data...
3) 3D-Beacons search finds nothing and is no longer an option in the Structure Chooser window.

Java Console output _sometimes_ has an ArrayIndexOutOfBoundsException:

Even though no 3D-Beacons models are presented in the Structure Chooser, if you then look at each sequence _individually_, there are 3D-Beacons models discovered for all sequences except for Q7XA98_TRIPR and O80429_MAIZE.

When the ArrayIndexOutOfBoundsException is not observed (when searching across all sequences), there are still no 3D-Beacons models presented.
