The LS is not compatible with the 0.11.0 CLI

Problem:
The LS fails to start with the following error:

The ino file exists under this location, but the name of the sketch file does not match the name of the container folder name. The CLI throws an error here: https://github.com/arduino/arduino-cli/blob/fff99af81a922eb89c01703373659b5983375093/arduino/builder/sketch.go#L128-L131

Solution: instead of copying the files under path/to/tmp/ino2cpp-${random} we copy to path/to/tmp/ino2cpp-${random}/sketchName where sketchName is extracted from the source.

We should also remove the <br>, looks like Theia no longer supports them.
