Some identifiers cause LookupServiceTests to timeout

[gaurav]

This following identifiers take more than 60 seconds to run lookup, causing it to timeout:

• CHEBI:22563
• CHEBI:26369
• UniProtKB:O75795
• UniProtKB:P07900
• UniProtKB:P08684
• UniProtKB:P13569
• UniProtKB:P16662
• UniProtKB:P19224
• UniProtKB:P22310
• UniProtKB:P51589
• UniProtKB:P54855
• UniProtKB:P56856
• UniProtKB:P82251
• UniProtKB:Q07837
• UniProtKB:Q16651
• UniProtKB:Q9HB55
• UniProtKB:Q9HBW0
• UniProtKB:Q9NPD5
• UniProtKB:Q9NZQ3

This makes it look like we can't lookup any UniProtKB identifiers, but UniProtKB:P24462 does work correctly.
