[FIX] sale_timesheet: remove the emoji in the demo data

Before this commit, when the database is launched on an Apple computer,
the demo data in sale_timesheet module cannot be installed because of
the emoji is not correctly managed by a OS version of Apple.

This commit removes the emoji to be able to launch an odoo database on a
Apple computer.
