Cannot upgrade from 1.11 to newer versions

[oanalavinia]

Steps to reproduce:

1. Install Office365 version 1.11
2. Try to upgrade to a newer version, e.g. 1.11.1 (or 1.11.2, 1.11.3)

Expected result:
Upgrade is done

Actual result:
Upgrade fails with the following error
Ranges [[2.4.11,]] and [[1.3.2,2.4.2]] are incompatibles

Investigation:
This is caused by #25. The fix made the app compatible with OIDC, which required net.minidev:json-smart [2.4.11,], but it become no longer possible to upgrade from older versions that had the [1.3.2,2.4.2] range defined

Until the issue is fix, the workaround would be to:

1. Uninstall net.minidev:json-smart
   This will also uninstall office365, as well as other apps that require this small extension, so make sure to install them back after
2. Install the new version of office-365
   Again, make sure to install back other removed extensions (e.g. OIDC requires this extension)
