[PATCH 17/19] [GSOC] ref-filter: remove grab_oid() function

<ff74fa9f2f2fb1ea77782254da74c2d0ce6c6bb8.1626090419.git.gitgitgadget@gmail.com>
In-Reply-To
<pull.993.git.1626090419.gitgitgadget@gmail.com>
From: ZheNing Hu <adlternative@gmail.com>

Because "atom_type == ATOM_OBJECTNAME" implies the condition of `starts_with(name, "objectname")`, "atom_type == ATOM_TREE" implies the condition of `starts_with(name, "tree")`, so the check for `starts_with(name, field)` in grab_oid() is redundant.

So Remove the grab_oid() from ref-filter, to reduce repeated check.
