PROEDITOR-53: Changed the way we set the workspace

Got rid of the `sketch` search parameter from the URL.

Rules:
 - Get the desired workspace location from the
  - `Path` defined as the `window.location.hash` of the URL,
  - most recent workspaces,
  - most recent sketches from the default sketch folder.
 - Validate the location.
 - If no valid location was found, create a new sketch in the default sketch folder.

Note: when validating the location of the workspace root, the root must always exist. However, when in pro-mode, the desired workspace root must
not be a sketch directory with the `.ino` file, but can be any existing location.
