[ASTERIXDB-2402][COMP] Allow AND for IsMissing in Groupby
AccessMethodUtils.findLOJIsMissingFuncInGroupBy()
looks for the not(is-missing($VAR)) pattern
in a group by, but failed to detect it if it is part of
an and, e.g. and(not(is-missing($VAR1)),not(is-missing($VAR2)))
This changes fixes this and adds a test case

> Issue Type: Improvement
> Reporter: Steven Jacobs
> Priority: Major
>
> When findLOJIsMissingFuncInGroupBy() in AccessMethodUtils looks for the
> not(is-missing($$VAR)
> expression, it fails to check select statements of the form:
> select (and(not(is-missing($$VAR1)), not(is-missing($$VAR2))))
> It only looks for
> select (not(is-missing($$VAR))
> which doesn't cover all cases.
