Use EXPECT_EQ directly instead of EXPECT_STREQ in InputMethodControllerTest

As the first step to deprecate WTF::CString, the bug has suggested replacing
EXPECT_STREQ with EXPECT_EQ. This CL replaces EXPECTED_STREQ with EXPECT_EQ
in the cases of both converting WTF::String to const char* to use EXPECTE_STREQ
and the expected string is ASCII.
