test_coding_dna_insertion failing in tests

Test case with query `LIMK2 c.2049_2050insA` is failing during tests, but gets expected value when using the local endpoint (`http://127.0.0.1:8000/variation/normalize?q=LIMK2%20c.2049_2050insA`). Public endpoint is getting the same result as test output.

Expected:
```
Allele(id=None, location=SequenceLocation(id=None, type=, sequence_id='ga4gh:SQ.7_mlQyDN-uWH0RlxTQFvFEv6ykd2D-xF', interval=SimpleInterval(end=2160, start=2160, type='SimpleInterval')), state=SequenceState(sequence='A', type='SequenceState'), type='Allele')
```

Actual:
```
Allele(id=None, location=SequenceLocation(id=None, type=, sequence_id='ga4gh:SQ.7_mlQyDN-uWH0RlxTQFvFEv6ykd2D-xF', interval=SimpleInterval(end=2223, start=2223, type='SimpleInterval')), state=SequenceState(sequence='A', type='SequenceState'), type='Allele')
```
