CLR Deployment TRUSTWORTHY issues in sqlproj

Question

When trying to deploy a CLR project that has been converted to a new sqlproj format, we get issues with TRUSTWORTHY that we never used to get. 
I notice that when I deploy to some of our databases the following gets included in the generated script:
IF IS_SRVROLEMEMBER(N'sysadmin') = 1
BEGIN
IF EXISTS (SELECT 1
FROM [master].[dbo].[sysdatabases]
WHERE [name] = N'$(DatabaseName)')
BEGIN
EXECUTE sp_executesql N'ALTER DATABASE [$(DatabaseName)]
SET TRUSTWORTHY OFF
WITH ROLLBACK IMMEDIATE';
END
END
ELSE
BEGIN
PRINT N'The database settings cannot be modified. You must be a SysAdmin to apply these settings.';
END
If I manually change the "TRUSTWORTHY OFF" to "ON" then it deploys correctly. 
Also, when we deploy the CLR project to other environment this block is not included in the generated script and we have to add it (with the ON/OFF fix) in order to deploy. 
In every case I've been onto the database and done the GRANT TRUSTWORTHY, SET TRUSTWORTHY ON, EXEC sp_configure 'clr enabled' , '1' etc that is usually needed to deploy the CLR projects. 
Can anyone give any guidance on the project settings or environment issues that cause the block to be included or absent from deployment. Is the ON/OFF value deliberate, and if so why does it only work for me if I manually change it?
Cheers

Oh No you Dint! AHHHHHHHHHH. What a waste of three hours! Can I still say "Someone should be shot" in 2015 or is the world too politically correct?
Bottom line: Yes your fixed worked: 
->TRUSTWORTHY is set to OFF by default (safe default) for SSDT projects, but that is configurable
->from
->project
>properties through Project Settings | Database Settings| Miscellaneous
THANK YOU.
What I was doing was setting the entire database to Trustworthy....never thinking that the CLR deployment would have been able to change the database settings for the entire database until it became apparent.
Keywords so others can find:
MSSQL database resets itself turns off TRUSTWORTHY  resets TRUSTWORTHY
Entire database false clr clr deploy deployment publish
