Fix line breaks for li

[mdimovska]

Fix line breaks for <li> elements:

• add line break only if addLineBreaks is true

• add line breaks only between <li> elements (do not set a line break for the last <li>, similar as it is done with paragraphs)

Hi @mdimovska and thanks for the PR 😄

Your CircleCI build is failing, probably because of linter errors. Please read the CONTRIBUTING document and it'll show you what command you need to run to fix that. You don't actually need to make any changes except the one to htmlToElement.js, so for simplicity you might want to just revert the others.

Please also add a test case that covers your change. Cheers!

Hi @richchurcher, sorry for breaking the build. I fixed the linter errors. About the testing, there is already a test case, which I changed a little in order to correspond to the change I made in htmlToElement.js.
Please check the PR again. Thanks :)

I have questions related to line breaks in other elements (sorry, this is not very related to this PR).

• Is there any specific reason why there are two \n for paragraph?
• Are these line breaks intended to behave similar as margins do (so that the separation between text looks nicer)? Or there is some other reason for this implementation?

Thanks :)

This is looking better. When I say add a test case, I mean one like this which specifically tests the addLineBreaks behaviour: https://github.com/jsdf/react-native-htmlview/blob/master/__tests__/HTMLView-test.js#L110-L126. So you want to make sure that it renders differently if that prop is false.

Regarding the breaks, I didn't write the original implementation but I can tell you that you can tweak margins fairly effectively if you turn 'em off: #142 (comment).

Any idea when this is going to be released?!
