hanging while getting lineage for LXPA01121130.1 about annotater HOT 1 CLOSED

After code fix, the exception that was occurring is revealed (thrown by Bio::DB::EUtilities)

------------- EXCEPTION -------------
MSG: NCBI esummary fatal error: Invalid uid LXPA01121130.1 at position=0
STACK Bio::Tools::EUtilities::parse_data bioperl/Bio-EUtilities/lib/Bio/Tools/EUtilities.pm:327

The issue was due to an endless do loop since an exception always occurred therefore $@ was always true. I added a limit on the maximum number of eutils requests to fix this issue.

Here is the HTTP response from NCBI if you manually use the eutils HTTP query
