Implement check equals expression for expr_equals

Now it's possible to check if a field equals an expression. This way it's also
possible to compare two expressions.
Tests cover generated sql-string, used by stored exprs and used in select
Move check if value is expression to better position

Now Compare-expressions are handled the same: getting value from "getFormattedValue()"
and checking if value is expression. If it's a expression do correct handling.
Refactored for simpler understanding
Move logic to prevent quoting for an sql-statement

If the compare-value was a expression it also got quoted, but then sql won't work.
Add convert from and to array for expression as value
mark failing test incomplete
