Add document URI as context to getDefaultFormatter

This way the default formatter will be resolved correctly in multi-root workspaces.
Beforehand only the workspace settings where taken into account.
Now the behavior is as expected, see eclipse-theia#13108 for an example.

Fixes eclipse-theia#13108.
