Fix updatenotification

[bugsounet]

Sometime, pm2 jlist don't send an json reponse
Catch error if happen

[bugsounet]

Note:

For me, best way is using pm2 library directly because with command line sometine we can have some pm2 warn (update warn for example) and it break response
but there is some moderate severity vulnerabilities with this library

@rejas: So, what can I do ?

[rejas]

@bugsounet do you have a link to that vulnarbility?

[bugsounet]

seams to be last current axios vulnerabilities

3 moderate severity vulnerabilities

[rejas]

Well, axios is probably only fixable until node-ical gets updated (see #3278) (but maybe we can also force the update). Aynway, thx for the fix!
