Evict project in user cache on save of project meta data

On saving of the project description and project options the project
is not evicted from the user cache (PerRequestProjectControlCache).
As a result the ProjectInfoScreen is showing the old data after save.
Only when the page is reloaded the new data is displayed.

This change evicts the project from the user cache when the project
meta data is changed, so that the ProjectInfoScreen always shows the
correct data.
