fix open cover reporter so that it uses unique ids over multiple modules

[corinblaikie]

The open cover output doesn't work with report generator as it has the same uid values for different files over multiple modules.

<ModuleName>Module.A</ModuleName>
<Files>
<File uid="1" fullPath="C:\code\testproject\src\Module.A\Example.A.cs" />
...
<ModuleName>Module.B</ModuleName>
<Files>
<File uid="1" fullPath="C:\code\testproject\src\Module.B\Example.B.cs" />

instead of

<ModuleName>Module.A</ModuleName>
<Files>
<File uid="1" fullPath="C:\code\testproject\src\Module.A\Example.A.cs" />
...
<ModuleName>Module.B</ModuleName>
<Files>
<File uid="2" fullPath="C:\code\testproject\src\Module.B\Example.B.cs" />

@corinblaikie thanks!!! I'm curious though, is this the only fix needed to get it working with ReportGenerator. Can you please post a screenshot of report generator showing a coverlet output, didn't test it myself so will love to see it

ReportGenerator seems to work with the coverlet open cover xml:
