varInspector keeps variables persistent after using %reset magic

[edridgedsouza]

If you reset the kernel with the %reset magic command, all of the previous variables are still present with their old values in the variable explorer. This doesn't appear to happen when the variables are individually deleted with del

Reproducible and Interesting.
Even new variables are not listed. I will look at what does %reset; but perhaps that it creates a new namespace and that the last one is still accessible. This would mean that perhaps varInspector needs to catch the %reset magic and restarts itself in that case;

[jfbercher]

The hypothesis in my previous comment (that %reset may create a new namespace) was wrong.

What happened was simply that some hidden variables and functions used by varInspector (to list all variables used by the current kernel) were cleared by the %reset, and therefore varInspector failed. In #1016 , the state of the refresh operation is checked, and in case of error (which occurs if the variables/functions used by varInspector are cleared), the extension is reinitialized.

Should be fixed by #1019
