Error message when installing an 1.6 APK with a previous installed 1.4 apk

We have noticed that if we install a new APK without uninstalling the previous app, the new app crashes a lot

@ifoche I have tested install 1.6 version from a 1.4 version and migrations is failing. Failing because the migration is created to be installed from the last version. For example:

• in 1.4 Table A does not exist
• in 1.5 we have created Table A creating dbflow model A with props (columns) 1,2,3
• in 1.5.1 we add column 4, adding a prop to dbflow model A (for new installations)and creating migration (for upgrade installation)
• in 1.6 we add column 5, adding a prop to dbflow model A (for new installations)and creating migration (for upgrade installation)

When you upgrade from 1.4 to 1.6 directly migrations fail because the table is created directly by dbflow model, then when migration is executed is failing by duplicate column error. We should modify this migration to verify previously if the columns already exist I wait until to talk with you and we decide if these changes are necessary or it's an avoidable upgrade use case
