Fix: use agent's home directory if available

- the project text field in the IDEs&Project panel is filled with
  `/home/coder/workspace` value.
- the home directory depends on the workspace template and the correct
  value can be found on the WorkspaceAgent data model
- if the value is missing from the agent - the code should not assume that
  coder/workspace exists.
- resolves #27
