Compile Output keeps all red after warning

When cmake project configured to compile with GCC, and then switch compiler to CLANG in Kit options - it compiles OK, but compiler ouptut parser doesn't update.

Steps to reproduce:

1. Configure a Kit in Qt Creator with GCC compiler

2. Clone https://github.com/VolodymyrZibarov/CompileOutputColorBug.git

3. Open project, configure, run cmake, build.

4. Go into options and change compiler from GCC to CLANG

5. Rebuild project

Expected result:

only lines with warning highlighted in red in compile output

Actual result:

all lines after warning highlighted in red, including linking:
