Species parameter is not passed from homepage

[ke4]

Steps to reproduce:

1. On the scxa home page search for a gene and also select species from the drop-down

Expected behaviour:
Search result is filtered by the selected `species

Actual behaviour:
Selected species getting ignored when searching for the search term.

I had to do some changes in the atlas-components repo, too.
PR: ebi-gene-expression-group/atlas-components#153
It has been reviewed and merged.

I also have to update the package.json files in scxa web app to use the latest components of

• scxa-gene-search-form
• scxa-cell-type-wheel-experiment-heatmap
  I am going to do this now.
