Fix equal_any() DB API helper

equal_any() query helper is meant to produce a WHERE clause combining
a few conditions with OR operator in order to select the rows for
which the given column is equal to ANY of passed values. In fact,
it uses AND operator instead of OR, which means that an incorrect
WHERE clause will be returned, if more than one value is passed to
equal_any().

This is caused by the fact that the or_() function from SQLAlchemy
expression language is used incorrectly: it accepts unpacked
instances of BinaryExpression, but a list of ones is passed.
Unfortunately, in 0.7.x and 0.8.x branches of SQLAlchemy passing
a list of values to or_() won't raise an exception immidiately,
and the result will be an iterable, which explains why we didn't
see equal_any() was actually broken before. Besides, equal_any() is
rarely used in our code base and the test didn't cover the case when
more than 1 value is passed to the function.

This effectively fixes the error when running Nova unit tests
with SQLAlchemy 0.9.x releases.
