RLS update breaks formatting

I think the latest RLS implements formatting in a different way. As a result Ctrl+Shift+F produces no effect.

How to reproduce:

• update to RLS from nightly-2019-04-11
• edit any valid .rs file and artificially alter the indentation
• attempt autoformat using Ctrl+Shift+F
• result: no changes
• expected result: text is indented correctly

Additional information: There is no error message in the RLS logs. It does appear that the format operation is returning just a list of changes lines rather than the whole formatted file.

{"jsonrpc":"2.0","id":"56","result":[{"range":{"start":{"line":5,"character":0},"end":{"line":5,"character":18446744073709551615}},"newText":"use gtk::traits::*;"}]}

"character":18446744073709551615 is definitely an erroneous value (character is supposed to be the “column” of the character. The bug is in RLS 😉

fixed with RLS in nightly-2019-04-14
