Cannot build on production and on Jenkins

[alagane]

When building for production, or with Jenkins, there is an error. It might be linked to https://github.com/linagora/jmap-client-ts
The jmap-client-ts directory inside node_modules does not contain the lib directory on production.

I was not able to reproduce the error locally, using the same npm 6.14.6 and node 12.18.3. Locally the jmaps-client-ts directory contains the lib directory.

Possible fix:
Remove the file restriction on package.json on jmap-client-ts (instead on using only lib)
Using a postinstall script on jmap-client-ts to build the project
Adding typescript dependency to esn-frontend-inbox to be able to build jmap-client-ts with the correct version

See npm/cli#2062

The problems is the prepare script of jmap-client-ts is not run, this is clearly a npm bug
Tried with npm 7.24.2 with different node versions :

• With node 10.24.1 ✔️
• With node 12.19.0 ✔️
• With node 14.19.0 ✔️
