Number: Compact formatting with significat digits fix

[shivijais]

Fixes: #821

Removed the logic of rounding the number twice - with a precision of {actual precision required + 2} and then again with the actual precision. This was causing wrong rounding off a number. For eg.

Globalize.numberFormatter({
        minimumSignificantDigits: 1,
        maximumSignificantDigits: 3,
    })(12.849872883)

Here the number 12.849872883 is first converted to 12.850 and then when finally rounded off becomes 12.9. But Ideally this should be formatted to 12.8.

@rxaviers Can you please take a look at this PR. The travis-ci is failing on timeout issue with https://github.com/SlexAxton/messageformat which is now moved to https://github.com/messageformat/messageformat

Since these are unit tests, you don't have Globalize available. You need to use format (according to the above tests).

Let's also add a test where 12850172883 becomes 12.9B

Thank you so far

Thanks for the quick fix. Tests are passing, build is failing simply because of commit message which I can fix.

Having said that, I want to be sure the code simplification in the round function doesn't cause any side effect and therefore I plan to review this again. It's on my end, I hope to do it soon and will update this PR.

@rxaviers any update on this?
