Fix EF warnings

[kichalla]

When E2E tests are run, there are bunch of warnings related to EF. Fix them:

[xUnit.net 00:01:28.1812638]         | Information: warn: Microsoft.EntityFrameworkCore.Infrastructure.IModelValidator[1]
[xUnit.net 00:01:28.1813102]         | Information:       No type was specified for the decimal column 'Price' on entity type 'Album'. This will cause values to be silently truncated if they do not fit in the default precision and scale. Explicitly specify the SQL server column type that can accomadate all the values using 'ForSqlServerHasColumnType()'. To configure this warning use the DbContextOptionsBuilder.ConfigureWarnings API (event id 'SqlServerEventId.DefaultDecimalTypeWarning'). ConfigureWarnings can be used when overriding the DbContext.OnConfiguring method or using AddDbContext on the application service provider.

@ajcvickers - can someone on your team take a look at this?

[Eilon]

@ajcvickers anything to do here for preview1? Or should we move to preview2?

[ajcvickers]

@Eilon Sent a PR for this 12 days ago. Hasn't been looked at yet. There is no functional change, just a change to be more explicit in configuration so that the warning that configuration is not explicit is not shown. The app will function the same way with or without the warning. So, as far as I am aware, there is no need to do this for any particular release, but also no reason not to do it.

[Eilon]

Ah ok let's just fix in 'dev' then, now that we've branched.

[ajcvickers]

@Eilon What's the process for getting a review on the PR? Does anybody own MusicStore?

[Eilon]

@kichalla signed off on the PR yesterday. He is Mr. Music Store.

[ajcvickers]

@Eilon Oops. Sorry. Missed that he signed off on it. Thanks!
