[TASK] Remove static cache in StorageRepository

Class StorageRepository parks static state in property
$storageRowCache. This is ugly and needs proper reset
functionality. However, the class is also a singleton through
AbstractRepository, so there is no need to make $storageRowCache
static in the first place. Just making the property non-static
keeps all the functionality, and removes the hard to
evict static state at the same time.

Resolves: #85647
Releases: master
