Handle exceptions from PyViCare library (#28536)

* ViCare: Handle exceptions from PyViCare library (#28072)

Sometimes Viessmann server failures or other connection problems may
lead to exceptions thrown when updating data.

This commit handles those exceptions with some error logging and
makes sure that the component does not break completely in that case.

* Remove unneeded returns
