tinyxml2 fails to install after being uninstalled

[calvertdw]

After having timnyxml2 uninstalled (to build an earlier version of Fast-RTPS which would not build if tinyxml2 was installed on the system) it will not reinstall.

Running regedit, navigating to Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Kitware\CMake\Packages\TinyXML2 and deleting the TinyXML2 keys fixes the problem.

This might be an odd converse case of #4.

The script responsible for conditionally removing registry key values is

choco-packages/package/tinyxml2/tools/chocolateyuninstall.ps1

Lines 6 to 10 in 7dd3629

	if (Test-Path $CMakeRegistryPath) {
	if (Test-Path $CMakeSystemRepositoryPath) {
	Remove-Item "$CMakeSystemRepositoryPath\$CMakePackageName"
	}
