remotenames: enable the storage config option if extension is enabled...

remotenames: enable the storage config option if extension is enabled Before this patch, the config option to store remotenames was set to False by default and remotenames extension does not set it True. So if you enable remotenames extension without setting 'experimental.remotenames=True', you won't get the remotenames. This patch makes remotenames enable the config option if then extension is enabled which makes sense. Differential Revision: https://phab.mercurial-scm.org/D3520
