If there is an exception when applying a migration, there will be an incomplete document at MigrationVersions collection

[TioLuiso]

That leaves the database in an inconsistent status.

I can think of different solutions:

• Delay the insertion of the MigrationVersion until the migration has been applied
• In case of an exception, insert in MigrationVersion the exception information, too
• In case of an exception, remove the entry in MigrationVersion
