Incorrect Project Task Start/Finish Dates when created from Project Template

[turtlemenace]

When using the "Create Project" function from the Project - Templates module, the expected Start/Finish dates are not found in the Project Tasks that are created in the new Project.

Steps to Reproduce

Using the Demo CRM
Create a new Project - Template and save
Add first task, with duration 5 days
Add a second Task, with duration 5 days and first task as predecessor
Add a third task, with duration 5 days, with no predecessor
Create a project from this template.
Turn on Consider Working days, and create another project from this template.

Expected Behaviour

1/ The third task should begin on the project start date.
2/ Switching off Consider Working days should change the behaviour of the tasks so they take 5 days instead of 7.

Actual Behaviour

1/ The third task starts on the day after task 2, despite not having any predecessor
2/ Switching on/off Consider Working days has no impact on the Project timing

Context

It makes it impossible to setup a Project Template with parallel workstreams on the Gantt view.
