Search for genes returns invalid results

[gromdimon]

Describe the bug
REEV has received numerous issues related to incorrect search results (bihealth/reev#584, bihealth/reev#572). Both of these issues relate to gene query resolution, which occurs in REEV by calling the annonars endpoint /genes/search?q=${query}. After a couple of requests, the problem turned out to be in the data sent from the annonars (the invalid response).

To Reproduce
Look into: bihealth/reev#584, bihealth/reev#572
Brief:
Some queries doesn't work at all:

• ENSG00000242029
• OR4K8P genomeBuild=grch37

Other return invalid result:
PREP: refer to bihealth/reev#572

Expected behavior
As described in previous issues, the search for gene should work properly.
