Database Projects March Release - Non-SDK project build fails

[zijchen]

• Azure Data Studio Version: 1.52.0
• SQL Database Projects extension version: 1.4.7

Steps to Reproduce:

1. Create non-SDK style project or open existing SSDT project. No need to add any files to the new project.
2. Build will fail with:

"/usr/local/share/dotnet/dotnet" build "/Users/benjin/SqlProj/TestLegacyProject/TestLegacyProject.sqlproj" /p:NetCoreBuild=true /p:NETCoreTargetsPath="/Users/benjin/.azuredatastudio/extensions/microsoft.sql-database-projects-1.4.7/BuildDirectory" /p:SystemDacpacsLocation="/Users/benjin/.azuredatastudio/extensions/microsoft.sql-database-projects-1.4.7/BuildDirectory"
stdout: /Users/benjin/SqlProj/TestLegacyProject/TestLegacyProject.sqlproj(55,3): error MSB4019: The imported project "/Users/benjin/.azuredatastudio/extensions/microsoft.sql-database-projects-1.4.7/BuildDirectory/Microsoft.Data.Tools.Schema.SqlTasks.targets" was not found. Confirm that the expression in the Import declaration "/Users/benjin/.azuredatastudio/extensions/microsoft.sql-database-projects-1.4.7/BuildDirectory/Microsoft.Data.Tools.Schema.SqlTasks.targets" is correct, and that the file exists on disk.
