Induced condenser doesn't work with where clause

[Dimitar Misev]

A query using test_grey3d (assumes domain [0:99,0:99,0:4]):

select condense + over i in [0:4]
   using a[0:99,0:99,i]
   where avg_cells(a[0:99,0:99,i]) > 30
from test_grey3d as a

fails with:

rasdaman error 300: Parsing error 300 in line 3, column 4: Unexpected name where.

It should correctly parse the where in the condenser, and then evaluate it: only the array slices for which avg_cells(a[0:99,0:99,i]) > 30 is true should be added up in the condenser.
