Returning false prevents the message from being processed by the future or by any other hook, which messes everything up. Fixes jupyterlab#8056

I reproduced this with stock jlab 2.0.1 as well. |

There was a bug in JLab 2.0.0 and 2.0.1 that prevented cell execution when recordTiming was enabled. You might be able to cut down on support issues if you just go ahead and require at least JLab 2.0.2. See jupyterlab/jupyterlab#8057 and jupyterlab/jupyterlab#8056

Description
When I set the recordTimings option to be true with
in the user preferences for the notebook, the "execution timings" get outputted to the cell metadata, but the kernel doesn't seem to actually execute the cell. For example, print("hello world!") won't print,
1+1won't output2, and the cell reports jibberish as having evaluated normally instead of causing an error.Reproduce
recordTimingto be true and saveExpected behavior
Notebook should run normally when execution timings are active.
