Using optional chaining with the boxed version of invalid causes a runtime error

[gregomite]

From Roku's documentation, the invalid value and its boxed version, CreateObject("roInvalid") are both treated as invalid; however, no other values are. See Optional Chaining docs.

brs> foo = CreateObject("roInvalid")
brs> ?foo
<Component: roInvalid>
brs> print foo?.bar
REPL(1,11-14): Member function not found in BrightScript Component or interface.
brs>

The expression print foo?.bar should print out invalid instead of the error, "Member function not found in BrightScript Component or interface.".
