Bug in "use Mojo::Base -role": conflicts about "has"

[aferreira]

If one tries to compose two or more roles built with use Mojo::Base -role, as in the example below:

package Boo; use Mojo::Base -role;
package Foo; use Mojo::Base -role;

Mojo::Base->with_roles('Boo', 'Foo')

the following error is encountered

Method name conflict for 'has' between roles 'Boo' and 'Foo', cannot apply these simultaneously to an object.

That happens because has is imported to the caller namespace after the package has become a Role::Tiny

vs

• line 87 https://github.com/kraih/mojo/blob/master/lib/Mojo/Base.pm#L87

That makes Role::Tiny to think has is a method which should be part of the role composition.
