Fix T69488: Hair particles: rekey disolves the hair then crashes

Caused by rB914427afd512.

Since above commit 'pe_get_current' checks for an active depsgraph. This
caused the skipping of handling
`PT_CACHE_EDIT_UPDATE_PARTICLE_FROM_EVAL`for everything calling
`PE_get_current` (this passes a NULL depsgraph as opposed to
`PE_create_current`). So we now pass a depsgraph here as well...

Note there are two RNA cases where we pass NULL, namely
- rna_ParticleEdit_editable_get
- rna_ParticleEdit_hair_get
I guess these should be fine though (no functional change to current
master)
