• Fixes an issue where the whole migration process might be terminated without an attempt to retry during Read-SCVMHosts on some exceptions
• Fixes an issue where a VM might be marked as unmigratable due to unusual VM object status which is actually repairable; from now on, the module tries to repair it and to retry the migration instead
• Improves debug output to log any exception before throwing out
