Predefined_TrialWaveFunction causes runtime error

Running the ALF from the master branch in projector couses the following runtime error:

At line 102 of file Predefined_Hop_mod.F90
Fortran runtime error: Attempt to DEALLOCATE unallocated 'this'

Error termination. Backtrace:

Where the offending line in Predefined_Hop_mod.F90:102 reads:

deallocate (this(1)%L_Fam, this(1)%List_Fam, this(1)%Multiplicity, this(1)%Prop_Fam )

Changing this to

deallocate (this(1)%L_Fam, this(1)%List_Fam, this(1)%Prop_Fam )
if( associated(this(1)%Multiplicity) ) deallocate(this(1)%Multiplicity)

fixes the error. So Multiplicity isn't set in Predefined_TrialWaveFunction.

@Francesco.ParisenToldin could you have a look at this? It's probably connected to your recent additions.
