RSRP-469271: Some TestNames with periods in them do not display properly in the test runner UI for .NET Core projects (netcoreapp2.0)

Some periods (but not all) appears to be treated like a namespace or category in ReSharper v 2017.3.5

This appears to be a .NET Core only behavior, as I recently converted this from regular framework, and had no such issues.

Test method:

public static IEnumerable<ITestCaseData> GetScheduleForResourcesAsync_ExceptionTestCases()
{
    yield return new TestCaseData(_id, DateTimeOffset.MinValue, DateTimeOffset.MaxValue)
        .SetName("Start = DateTimeOffset.MinValue, End = DateTimeOffset.MaxValue returns 400 BadRequest");
}

Here's the full csproj:

<Project Sdk="Microsoft.NET.Sdk" ToolsVersion="15.0">

  <PropertyGroup>
    <TargetFramework>netcoreapp2.0</TargetFramework>
