"data" from faMesh same registration as fvMesh

Functionality to add/problem to solve

faSolution constructs 'data' database. This is the same name as that from fvSolution.

Run e.g. liquidFilmFoam/cylinder with

DebugSwitches
{
    regIOobject     2;
    objectRegistry  1;
}

and you'll see

--> FOAM FATAL ERROR: (openfoam-2302 patch=230110)
failed to register object ".../tutorials/finiteArea/liquidFilmFoam/cylinder/system/data" the name already exists in the objectRegistry

Proposal

Not sure if it is a problem. Does mean that items registered on data need to have different names.
