Squish: Fix tst_CSUP02

Squish (and therefore the test) "is typing" too fast
which breaks some assumption and the (nowadays?) normal
behavior of the CppEditor.
Fix this by introducing a delayedType() function to
be more realistic when doing this test.
Also removes a workaround for QTCREATORBUG-18769 as
this seems no more valid at all.
