[Bug] Compare-to is broken for Evolution: Conversion

[atom-box]

What happened?

Customer reported, and I reproduced in demo.matomo.cloud.

When viewing the Evolution here: Ecommerce >> Overview >> Conversion The evolution graph is totally blank.

What should happen?

The evolution, comparison, should populate normally: not be blank.

How can this be reproduced?

1. For a site which has Ecommerce data, and conversions, go in Matomo interface to Ecommerce >> Overview >> Conversion
2. Choose in date: Year:compare or daterange:compare
3. In the evolution, choose Conversion.

(Note: the feature is NOT broken for day comparison. The feature is also NOT broken for comparing
