Incorrect calculation of amino acid translations for a circular sequence

A region on a circular sequence that joins the end and the start of the sequence should be treated as continuous, i.e. the joined sequence parts should be concatenated and the amino acid translation should be calculated for the concatenated parts.

Scenario:

1. Open “_common_data\cmdline\DNA_circular.gb” 
2. Click "Show/hide amino acid translations > Translation selection"
3. Select the following region "1..10, 740..744".
   Expected result: the selected strand translation is "LS*LP".
   Actual result: the selected strand translation is "LLIT".
