[nongnu] elpa/drupal-mode 47fda0a38a 287/308: Ignore errors in `drupal/gxref-get-function-args`

[ELPA Syncer]

branch: elpa/drupal-mode
commit 47fda0a38a5b197f4606137d9c3b7d44aaeaa886
Author: Arne Jørgensen <arne@arnested.dk>
Commit: Arne Jørgensen <arne@arnested.dk>

    Ignore errors in `drupal/gxref-get-function-args`
    
    `drupal/gxref-get-function-args` would throw an error if the symbol was
    not in the GTAGS file (because we assumed `xref-item-summary` would
    operate on an eieio object).
    
    Instead cluttering the code with even more checks we just ignore errors.
