Fixed testAutofillAndSave_withExternalViews_loadWebViewFirst

This test was failing on automotive because the dataset picker for OUTSIDE1 was covering the
password field; hence, when the test case used the UI automator to press the latter, it actually
triggered autofill for the former.

The solution was to clear focus before each operation.
