Add unused needs_reinit parameters to ignored parameters

[hammannr]

This is another tiny PR to improve the template caching behavior.

So far, we specify all shape and index parameters that are not used by a source in the dont_hash_settings. However, wit this we're missing shape parameters such as the WIMP mass, which is usually implemented as a needs_reinit parameter. By including it now we can reduce the number of duplicated cached histograms.
