declaring a symlink should not alter the default symlink to current module

[MartyEwings]

This code

puppetlabs_spec_helper/lib/puppetlabs_spec_helper/tasks/fixtures.rb

Line 110 in 01886e8

fixtures['symlinks'] = auto_symlink if fixtures['symlinks'].nil?

prevents the use of symlinks section of the fixtures file for any other purpose than self reference for example:

symlinks:
peadm_spec: "#{source_dir}/spec/fixtures/modules/peadm/spec/acceptance/peadm_spec/"

would mean the code above would not also include this in the fixtures

symlinks:
<module_name>: "#{source_dir}"

It would be preferred if instead of a check and replace

fixtures['symlinks'] = auto_symlink if fixtures['symlinks'].nil?

that fixtures['symlinks'] wold be merged with auto_symlink to prevent loss of testing context
