Fix flaky content.browser.input.ImeTest#testPasteLongText.

ImeTest#copy() is an asynchronous method. After calling it, we should
wait for the clipboard get updated. Otherwise, we may paste the text
from other tests (like ImeTest#testImePaste) when we call ImeTest#paste().

Before applying this patch, the failure rate is ~12/40 . After that, it
decreases to 0/1000+.
