Search or URL lookup for some genes and/or ensembl gene_ids fails to render a page

[Nicolai-vKuegelgen]

Describe the bug
When trying to look up some genes (either by name or by ensembl gene id), REEV may fail to render a proper page (possibly instead of giving a "This gene_id can not be found" result).
I have so far found two different instances of this issue:
A) Some gene_ids are not found when searched for in REEV, but when when trying to access them by URL (https://reev.bihealth.org/gene/<gene_id>), REEV tries to render a result page instead of giving the "empty search result".
Examples: ENSG00000242029, ENSG00000241257
B) Some genes seem to be present in the REEV db (apparent because searching for their gene_id redirects to a URL with the gene name), but do not render to a meaningful result page.
Examples: RLIG1P2 / ENSG00000244561; MIR4445 / ENSG00000265956; OR4K8P / ENSG00000266693; RNU6-1210P / ENSG00000200645

To Reproduce
Steps to reproduce the behavior:
Either

1. Search manually for one of the gene names or ids listed as examples above on https://reev.bihealth.org/
   or
2. Use a direct URL to look them up: https://reev.bihealth.org/gene/<gene_id/gene_name>

Expected behavior
Genes without any information in the REEV database should just give that information. Genes, which are present in the db, should render at least minimal Information
