Labels in agent inspector are not visible

[lesquoyb]

Describe the bug
Since recently the inspect view of an agent doesn't display the name of inspected variables:

the left column should contain the names but it's empty.
The tooltip is work though:

In the console I have this error stack, but it is right when I run the simulation, before opening the inspector view, I don't know if it's related. No new error message when I open the inspector:

Key released: 	

when closing the simulation with this view still open I get this message, which may or may not be linked but it also seem like a (minor) bug:

An internal error has occurred.
Cannot invoke "gama.core.kernel.simulation.SimulationClock.getCycle()" because the return value of "gama.core.runtime.IScope.getClock()" is null

To Reproduce
Steps to reproduce the behavior:

1. open any model with agents
2. open the inspector on one agent of the simulation
3. See error

Expected behavior
We see the labels as it was the case before
