CLOUDSTACK-4645: There is no upgrade path from 4.1.1 to 4.2.0

Description:

    Simpler fix to support upgrade path from 4.1.1 to 4.2.0
    by adding a 4.1.1 string in the db update version range.

    Commit # d1642a489ce76e055d60b2caf3ccfe4bb136b745 introduced a duplicate
    user_vm_view view in the schema-410to420.sql script. Removing the first
    occurrence of that view, since whatever QA has been testing until now
    would have used the duplicated view that gets created after the first one.
