SonarQube analysis crashes when i-Code crashes

[begarco]

Describe the bug
Internal errors in i-Code checker make the analysis crash.

To reproduce
Run the SonarQube analysis on a file containing a known source of bug and with which i-Code throws exceptions.

Expected behavior
The plugin should:

• log i-Code error
• save a "parsing error" in SonarQube
