Send absolute file paths to 'rc' command
Send absolute file paths to 'rc' command

Currently all commands are using the '--absolute-path' command line
option to the 'rc' command which means that a file location will be
taken as absolute. However the rtags#getCurrentLocation() function we
are using plain 'expand' which gives back the pwd relative path of the
current buffer.

Add the ':p' modifier to the expand command in the
rtags#getCurrentLocation() function so that it will pass absolute paths
to the 'rc' command.
