The PackAddsCorrectFilesForProjectsWithOutputNameSpecified test fails due to assembly name not being overridden

[v-wuzhai]

Describe the bug

In the test PackAddsCorrectFilesForProjectsWithOutputNameSpecified, the output assembly name is specified as LibraryWithOutputAssemblyName. The test verifies that the generated .nupkg and .symbols.nupkg files contain the correct files, specifically MyLibrary.dll and MyLibrary.pdb in the lib/netstandard1.5 directory.

However, the test currently fails because the test project does not correctly override the assembly name. As a result, the expected files are not found in the generated packages.
