az sql db update doesn't work if --edition Basic --service-objective Basic

### Type of issue

Code doesn't work

### Reference command name

I use `az sql db update` quite a lot as I have a script that scale databases.

I have no problem running it and scale Azure SQL Database to whatever tier like:

`az sql db update -s MyServer -g MyResourceGroup -n MyDatabase --edition Standard --service-objective S2 --subscription "MySubscription"`

Problems arrive when I run something like:

`az sql db update -s MyServer -g MyResourceGroup -n MyDatabase --edition Basic --service-objective Basic --subscription "MySubscription"`

In that case the database won't scale and returns the error:

`Error | ERROR: (InvalidMaxSizeTierCombination) The tier 'Basic' does not support the database max size '268435456000'.`

But then I scale from `S0` to `Basic` form the Portal and everything works fine.

You don't believe it?

### Feedback

There is a bug in the AZ SQL module when scaling to Basic.
For all other edition and tier there is no problem
