qapi/expr.py: Check type of union and alternate 'data' member

Prior to this commit, specifying a non-object value here causes the QAPI
parser to crash in expr.py with a stack trace with (likely) an
AttributeError when we attempt to call that value's items() method.

This member needs to be an object (Dict), and not anything else. Add a
check for this with a nicer error message, and formalize that check with
new test cases that exercise that error.
