Hash :13ac4dfb Message :gl_tests:DrawArraysThenDrawElements: glFinish instead of swap
Later in the test we read from the backbuffer to confirm that the
triangles were drawn correctly, but without EGL_BUFFER_PRESERVED
the content of the backbuffer is undefined.
Since glReadBuffer is not supported in GLES2 don't swap, instead to
a glFinish to force the drawing in each iteration.
