[dependabot-preview]

Bumps geocoder from 1.4.9 to 1.5.0.

Changelog

Sourced from geocoder's changelog.

1.5.0 (2018 Jul 31)

• Drop support for Ruby <2.0.
• Change default street address lookup from :google to :nominatim.
• Cache keys no longer include API credentials. This means many entries in existing cache implementations will be invalidated.
• Test lookup fixtures should now return coordinates and NOT latitude/longitude attributes (see #1258). This may break some people's tests.
• Add support for :ip2location lookup (thanks github.com/ip2location).
• Remove :ovi and :okf lookups.
