Refactor AwAutofillTest

1) Move WebServer instantiation and shutdown into setUp() and tearDown()
2) UMATestHelper to have mWebServer
3) Move field block to the beginning of UMATestHelper
4) Reformatting due to git cl format

This makes the test more readable at the expense of doing additional
WebServer setUp/shutDown for a couple of test cases.

Otherwise, there is no other logic change.

Bug: 1065160
Test: AwAutofillTest test time remains the same. Doesn't seem to add new test flakiness.
