Removed hard-coded /p4 path for server.id file location. This fixes "-test" mode so server.id file is written to the correct location. Without this it is written to /p4 where there could be an installation with the same instance ID. In that case the server.id file could get overwritten with different data. If there is not an existing instance an error message would be displayed. Now neither of these should occur :-)
Also fixed some typos.
