Handle module names with spaces

[ampeixoto]

Hello,

My Bitrise workflow is failing to run Android unit tests with the following error:

I lookind into the source code of the android-unit-test step (https://github.com/bitrise-steplib/bitrise-step-android-unit-test/blob/master/main.go) and I think a found the problem in the parseVariants() method of the "task.go" file (https://github.com/bitrise-io/go-android/blob/master/gradle/task.go).

Because when I run the command gradlew tasks --all --console=plain --quiet I get lines like the following:

my app:testMyvariantDebugUnitTest - Run unit tests for the myvariantDebug build.

So, as you can see, my module name contains a space character, and in the parseVariants() method the code seems not to handle this very well:

// l: " lintMyflavorokStaging - Runs lint on the MyflavorokStaging build."
l = strings.TrimSpace(l)
// l: "lintMyflavorokStaging - Runs lint on the MyflavorokStaging build."
if l == "" {
    continue
}
// l: "lintMyflavorokStaging"
l = strings.Split(l, " ")[0]
var module string

split := strings.Split(l, ":")

Am I seeing this right or am I missing something?

UPDATE
I renamed the module name to remove the space, and it works now. So that seems to be the problem.
