AEM64 enable_crxde fails if already enabled

[mbloch1986]

In some cases enabling crxde may fail if it's already enabled and the sling config /app/system/config/org.apache.sling.jcr.davex.impl.servlets.SlingDavExServlet exists.

Steps to reproduce:

• Create AEM 64 Stack with enabled crxde
• Run enabling CRXDE Job via Stack manager messenger
• It may fail

Workaround:

• Remove Crxde config /app/system/config/org.apache.sling.jcr.davex.impl.servlets.SlingDavExServlet manually
• Run enabling CRXDE Job via Stack manager messenger again
• It should be successful

Environment:

• AEM64 SP2
• AEM AWS Stack Builder 3.2.1
• Packer-AEM 3.3.0
• Enabled CRXDE in config profile
