DockerUri.Build call does not tag the images

[dil-bkis]

Hi!
I found the following issue while using the package. It's nothing serious, but if you have a bit of time, please take a look.
Thanks for everything, have a nice day!

ISSUE:
When using the DockerUri.Build(...) method with name, tag and work directory the created image is not tagged with the specified values. The workaround is to add a ContainerBuildParams object to the call with a non-null Tags array.

        // NOT TAGGED
        var buildResult = docker.Host.Build(
            "my-app",
            "latest",
            "..\\..\\MyApp");

        // TAGGED
        var buildResult = docker.Host.Build(
            "my-app",
            "latest",
            "..\\..\\MyApp",
            new ContainerBuildParams { Tags = Array.Empty<string>() });

The offending code from the package seems to be the following:

    public static CommandResponse<IList<string>> Build(this DockerUri host, string name, string tag, string workdir = null,
      ContainerBuildParams prms = null,
      ICertificatePaths certificates = null)
    {
      if (null == tag)
      {
        tag = "latest";
      }

      if (string.IsNullOrEmpty(workdir))
      {
        workdir = ".";
      }

      var options = string.Empty;
      // NOTE:
      // If prms or the Tags property within is null, the tags are not added.
      // That's why adding a ContainerBuildParams with an empty Tags array works.
      if (null != prms?.Tags)
      {
        // ANOTHER NOTE:
        // This comparison is also a bit weird, because the prms.Tags will contain full 'name:tag' values,
        // but the tag will only contain the 'tag' itself.
        if (!prms.Tags.Any(x => x == tag))
        {
          options = $"-t {name}:{tag}";
        }
      }

      if (null != prms)
      {
        options += $" {prms}";
      }

      return
        new ProcessExecutor<StringListResponseParser, IList<string>>(
          "docker".ResolveBinary(),
          $"{host.RenderBaseArgs(certificates)} build {options} {workdir}").Execute();
    }

Hi @dil-bkis and thanks for your good bug report!

I'll add it to my TODO list.

Cheers,
