Improve Editor fails to open journey

[nikku]

Note: This is actually not a bug but a feature request. Read more in the Expected Behavior section.

Describe the Bug

I cannot open the BPMN editor on Mac OS, starting with v3.0.0-beta.0.

Steps to Reproduce

• Download the latest beta release
• Unpack it (or install DMG)
• Open the editor
• See that the editor window is blank

Later in the process, we found out:

• Inspect the logs
• Realize an old version of token simulation is in the search path (cf. Token simulation not working with v3.0.0 #1193)
• Realize that we do not properly handle tab errors (Improve Tab Error handling #1214)
• Disable plug-ins (complicated manual process right now) and see all is good

Expected Behavior

• Still show UI (indicating a bug) Improve Tab Error handling #1214
• Log bug / error with relevant context Tab errors don't provide relevant context #1176
• Give users a simple way to restart the app without plug-ins (if we detect that plug-ins may be the cause of the issue) Improve Editor fails to open journey #1252

Environment

Please complete the following information:

• OS: MacOS, 10.14.3 (works fine on current Arch Linux)
• Camunda Modeler Version: v3.0.0-beta
