* src/register/ledger-core/*: gnc_table_layout_get_cell() doesn't

look at the current cursor, so the multi-currency code was acting
	  all the time, instead of only in registers that needed to be corrected.
	  Fix the code to only apply the multi-currency changes to the correct
	  register types (e.g., NOT stock registers).  Fixes 102549.
