Rename 'row' to 'uuid' in the relations schema

resolve #14

[johanjanssens]

@ercanozkaya Can you review this? I wanna get rid of the row column name it's too generic. Since tag relations work using uuid I think using uuid as the column name makes a lot more sense.

@johanjanssens There is one thing that might be a problem in the future. If we add a uuid column to tags table itself as we do/plan to do with every table the joins are not gonna work anymore. In that sense row is a better signal that it's a foreign key no?

[johanjanssens]

@ercanozkaya You could argue that point. In activities we have started to use 'resource_id' instead of row. See: https://github.com/joomlatools/joomlatools-framework-activities/blob/feature/1-denormalization/resources/install/example.sql#L28

The thing with tags is that row makes less sense as we are not using a row id, but a uuid. Not a fan of row, not declarative enough

@johanjanssens I'm happy with resource_id. Makes more sense if we are using it in activities too.

@ercanozkaya Can I assign this to you to handle? This change also gonna need to be merged to Kodekit Platform.
