test: move to ASSERT_NULL and ASSERT_NOT_NULL test macros
Moving to new style test macros will make debugging easier in case
of test failure and improve redability. This commit will replace all
ASSERT macros matching the statement:
`ASSERT(identifier (== or !=) value);`
to:
`ASSERT_(NOT_)NULL(identifier);`
