Paragraph block is prematurely removed on backspace event

[mkevins]

When all text is deleted from a paragraph, the block is removed prematurely. This issue has been encountered on Android Emulator, but may not occur on a physical device.

Steps to reproduce:

• Place caret at the end of the "Hello World!" paragraph (after the '!')
• Press [backspace] 12 times

Expected result:
The (empty) paragraph block remains focused, with the placeholder text ("Start writing...") visible.

Actual Result:
The paragraph block is removed. The focus changes to the previous block.

This behavior is mentioned in #699, and may be related to #783.

I can confirm this happens on WPAndroid alpha-160

I've seen a crash that seems related:

1. Create a new post
2. Tap the link button and enter some url and text
3. Close the link UI
4. Press backspace enough times to delete the whole link
5. Crash

I've seen it happen with other combinations of typing and links, but this were steps where I could reproduce consistently.

Tested on WPAndroid alpha-160

So is it fine to close this as a duplicate of #699?

Thanks @marecar3 ! I wasn't 💯 sure if the two issues would be solved by the same PR, so I split out this issue. Glad that the PR solves both! I'll test it out.

I just tested it (on the Android emulator), and it indeed solves the problem. Thank you!
