possible regression in uniformFixedValuePointPatch?

In tutorials/basic/overLaplacianDyMFoam/heatTransfer I'm getting some very odd output which I think could be related to this commit: 0987898f5c1678

I initially thought it might be related to the generic point patches since reconstructPar was failing when fill-nan is set. The values it reconstructs for the pointDisplacement right1 boundary are scalars, not vectors.

Backtracking some more, it seems that the original decomposed fields are a bit odd.

In 1812: processor0/0/pointDisplacement.right1

right1
{
    type            uniformFixedValue;
    value           nonuniform 0();
    uniformValue    constant (0 0 0);
}

In develop: processor0/0/pointDisplacement.right1

right1
{
    type            uniformFixedValue;
    uniformValue    ( 0 0 0 );
}

At later times this looks different again. Eg, processor0/0.5/pointDisplacement.right1

1812:

right1
{
    type            uniformFixedValue;
    value           nonuniform 0();
    uniformValue    constant (0 0 0);
}

develop:

right1
{
    type            uniformFixedValue;
    value           nonuniform 0();
    uniformValue    nonuniform 0();
}

When this is reconstructed, the generic point patch process the entries quite badly. Even the output for value does not look correct.
