[nongnu] elpa/helm 385368ed8e 1/3: Use helm-alive-p in helm-grep-filter-one-by-one

[ELPA Syncer]

branch: elpa/helm
commit 385368ed8e9622c7344a40fc62ecc277d7210da1
Author: Thierry Volpiatto <thievol@posteo.net>
Commit: Thierry Volpiatto <thievol@posteo.net>

    Use helm-alive-p in helm-grep-filter-one-by-one
    
    Previously we were using (null (eq major-mode 'helm-grep-mode)) which
    work fine in either helm of a helm-grep-mode buffer, but the test
    returns t as well in any other buffer which prevent reverting a buffer
    from somewhere else.
