Variant expansion initially empty when referenced from settings.json

[allsey87]

Brief Issue Summary

Using variants in settings.json such as:

"cmake.buildDirectory": "${workspaceFolder}/build-${variant:buildFor}-${variant:buildType}",

results in an empty directory called build-- being created when I select a variant from the GUI. Once this process is complete, I get the proper directory being created and used for the build, but this empty, incorrectly named build directory is left behind.

Expected:

No directory build-- should be created. I guess this could be solved by parsing and loading cmake-variants.json before processing settings.json.

I would like to mention that also variant expansion does not work in tasks.json

{   "version": "2.0.0",
    "tasks": [
        {
            "label": "echo test",
            "type": "shell",
            "command": "echo ${variant: myvariantname}",
            "problemMatcher": []
        }
    ]
}

This will always output an empty string instead of the actual value.
Is there a workaround?
