[IMP] sale_{project,timesheet}: set SOL in project even if no partner set

Before this commit, when the user configures his project and wants to
set a default SOL, he must first define the customer of the project
before setting the SOL. Same process for the SOL in employee mappings.

This commit allows the user to choose a SOL as default SOL or the one in
the employee mappings in his project even if no customer is defined into
it.
