Remove unnecessary 'IN vs ==' sql query branches

Remove unnecessary 'IN vs ==' sql query branches

Removes some branches in the codebase that switch
queries depending on whether a WHERE match is against
a single criteria or multiple criteria. For multiple
options an 'IN' statement was used and for a single
option an '==' was used.

This is completely unnecessary complexity and brancing
in our codebase because the 'col IN items' statement is
just a nice syntax offered by SQL that gets converted into
'col==item1 OR col==item2 OR col==item3...' statements
under the hood. So in the case of one item, 'WHERE col IN "F"'
is the same as 'WHERE col = "F"'.
