[PATCH v2] user32/tests: Use winetest contexts to simplify test_string().

[Francois Gouget]

This ensures all traces have the relevant context information, in
particular the OpenClipboard() checks, and simplifies the ok() calls.

v2: Delay the winetest_push_context() call to avoid trouble with the 
    lone continue statement.
