Tests expect TypeError, should just be 'a dynamic error'

[johnniwinther]

These tests expect TypeError to be thrown:

Language/03_Overview/1_Scoping_A02_t05
Language/03_Overview/1_Scoping_A02_t06

but the spec only mentions that 'a dynamic error occurs'. (§16.12.1 New)

Fixed. Excessive exception type check removed. Please see 3776223
