Fix flakyness with TextfieldViewsModelTest.Clipboard.

Fix flakyness with TextfieldViewsModelTest.Clipboard.

Set the clipboard text initially rather than using
whatever happened to be in the clipboard at the time
of the test.

BUG=none
TEST=Copy some non-ASCII text before running TextfieldViewsModelTest.Clipboard.
Then, run the test. It should not fail.
