Masayuki Nakano 8c3ba237c6 Bug 503838 - part 1: Remove following <br> element for empty line when it becomes unnecessary with inserting text r=m_kato
`HTMLEditor` does not remove padding `<br>` element for last empty line when
it becomes unnecessary.

This patch removes it when inserting some text into a text node and it's
followed by a padding <br> element.
