can not create project when a subgroup with the same name under the same level exist
Summary
can not create project when a subgroup with the same name under the same level exist and vice versa. the ui promotes this tip: The form contains the following errors:
- Route path has already been taken
- Route is invalid
Steps to reproduce
- create a subgroup under group
subtest1, named withsubtest2, for example - under group
subtest1, click the buttonNew projectto create project, with namesubtest2
What is the current bug behavior?
then error occurs as snapshot below

What is the expected correct behavior?
no error; Because gerrit support this feature, subgroup name and projectname under the same group can be same. and serveral suppliers or customer use gerrit as scm, not gitlab. and we need keep synchronization between these two scm system(gerrit and gitlab). if gitlab could not support this feature, the synchronization between gerrit and gitlab is unimaginable for there are hundreds of projects to synchronize, moreover, the folder organization structure of these hundreds of projects do not always stay the same
