lib/helpers: Don't rm "$profile_path" before writing to it

When the file is being re-created, we write to it, instead of appending to
it. So, the rm here is unnecessary and prevents users from linking the profile
file to another location that is potentially under version control. For
instance, once could link to a profile file located at
"$BASH_IT_CUSTOM/profiles/*.bash_it".
