Steps to reproduce:
1. Download and open attached project.
2. Download and open folder named "script_testes".
3. Drag and drop script named "Camera_teste.js" to the "Assets" folder and press "I Made a Backup. Go Ahead!" button.
4. Notice that the "Console" window informs:
"Finished updating scripts / assemblies"
5. Drag and drop script named "Velocidade_Anims.js" to the "Assets" folder.
6. Notice that the "Console" window outputs:
"Assets/Velocidade_Anims.js(8,17): BCE0048: Type 'UnityEngine.Component' does not support slicing."
"Assets/Velocidade_Anims.js(12,17): BCE0048: Type 'UnityEngine.Component' does not support slicing."
(all these compiler errors should be fixed before entering playmode)
7. Delete these two scripts from the "Assets" folder.
8. Import scripts in different order (firstly, import script named "Velocidade_Anims.js", then, import script named "Camera_teste.js").
9. Notice that the "Console" window outputs:
"Finished updating scripts / assemblies"
(there are no compiler errors visible)

Expected result:
Importing scripts in different order should not have such an impact on API updating.

Reproduced with:
5.1.0f3, 5.2.4f1, 5.3.5f1, 5.3.5p1, 5.4.0b18.
