contacts_get raises MeshKernelError in meshkernel 4.0.1

[veenstrajelmer]

Describe the bug
contacts_get in meshkernel 4.0.1 raises "MeshKernelError: MeshKernelError: Exception of type 'MeshKernelError': The The contacts have not been computed.". The previous meshkernel 3.0.0 returned an emtpy "<meshkernel.py_structures.Contacts at 0x1c448670110>" instead.

To Reproduce

from meshkernel import MeshKernel
mk = MeshKernel()
mk.mesh2d_get() # returns `<meshkernel.py_structures.Mesh2d at 0x27261d77110>`
mk.contacts_get() # raises error instead of `<meshkernel.py_structures.Contacts at 0x1c448670110>`

Expected behavior
Returning contacts, empty or not.

Version info (please complete the following information):

• OS: Windows 10
