Remove end slash from rootPath / rootUri / workspaceFolders

[zulus]

While fighting with eclipse-wildwebdeveloper/wildwebdeveloper#1520 and analyzing different behaviors in Typescript LS between VScode and Eclipse, I realized that typescript is not able to correctly find projectRootPath.

It's because rootPath/rootUri/workspaceFolders always ends with "/" (at least on mac). So when Typescript LS search for projectRoot by checking (in loop) if documentPath starts with rootPath + DIR_SEPARATOR is not able to find it

@zulus is this still an issue? TS support seems fine to me with current versions of Eclipse, LSP4E and wildwebdeveloper
