Fix cts fail for InlineLoginActivityTest

For InlineLoginActivityTest#testScrollSuggestionView:
Due to the total width of inline suggestions is shorter than the
width of TV device, it will not be able to be scrolled. It would
better add more inline suggestions to let the total width of inline
suggestions is longer than the width of TV device, then it will
be able to be scrolled during testing.

For InlineLoginActivityTest#testSwitchInputMethod:
Because it doesn't set the second Autofillable Activity's reponse within
InlineLoginActivityTest#testAutofill_SwitchToAutofillableActivity, then
it will cause InlineLoginActivityTest#testSwitchInputMethod fail. It
would better set the second Autofillable Activity's reponse within
InlineLoginActivityTest#testAutofill_SwitchToAutofillableActivity.
