msbuild does not build precompiled header before building source file if UseMultiToolTask=true and path to the pch.h is relative

### Issue Description

I have the following project:
```
pch.h
pch.cpp
test/in-sub-folder.cpp
Directory.Build.props
```
The content of the `Directory.Build.props` is
```xml

true

```
and the `test/in-sub-folder.cpp` file has a `#include "../pch.h"`

If I try to compile the project I get
```
03:08:37:193 Rebuild started at 03:08...
03:08:37:252 1>------ Rebuild All started: Project: TestCcache2, Configuration: Debug x64 ------

```

### Steps to Reproduce

You can find an example project here: https://github.com/autoantwort/msbuild-bug-repro

### Expected Behavior

The file in the subfolder should be compiled after the precompiled header is compiled

### Actual Behavior

The file in the subfolder is compiled before the precompiled header is compiled

### Analysis

It seems that msbuild misses the dependency on the precompiled header file.
