How to reproduce:
1. Open the user's attached project ("ShaderErrorBug.zip")
2. Call menu Bugs/Reproduce Bug
3. See "False" log in the console (the result of ShaderHasError call)
4. Select ShaderWithError shader in the Project tab
5. Call menu Bugs/Reproduce Bug again
6. See True in the console (the result of ShaderHasError call)

Expected results: "ShaderHasError" method returns "True" without manual Shader selection when shader has errors
Actual results: "ShaderHasError" method returns "False" unless the Shader which has errors is selected

Reproducible with: 2019.1.0f2, 2019.2.0a13
Couldn't test 2017.4, 2018.3 and up to 2019.1.0b1 because of missing "ShaderHasErros" method

Notes:
1. After the Shader was selected once, "ShaderHasErrors" will work as expected, until the Editor is re-opened or all assets are re-imported
