Describe the bug

When running a specific test by clicking the run test link above a test func, the command is executed:

Running tool: /home/asare/.gvm/gos/go1.14.2/bin/go test -timeout 10s gitlab.com/asare/project -run ^TestFuncName$ -v -count=1

when then running the Go: previous test action it runs the last test without the -run flag, resulting in the entire package being tested.

Steps to reproduce the behaviour:

1. create a new test file with something like:

package random_test

import "testing"

func TestRandom(t *testing.T) {}

2. Click on run test above TestRandom
3. Run the Go: Test Previous action from ctrl+shift+p
