`store-secret` hangs when file does not exist

[ZZiigguurraatt]

If run

lndinit -v store-secret --batch --overwrite --target=k8s --k8s.namespace="default" --k8s.secret-name="${TAPRPC_SECRETS_NAME}" "${TAP_DIR}"/*.macaroon

and no macaroon files exist, lndinit hangs indefinitely, even once a macaroon file is created.

Also, if I run

lndinit -v store-secret --batch --overwrite --target=k8s --k8s.namespace="default" --k8s.secret-name="${TAPRPC_SECRETS_NAME}" "${TAP_DIR}"/bogus_file

it also hangs indefinitely.

I think that either lndinit should immediately fail if the file does not exist, or once the file exists, it should continue. Either one of these approaches is better than the current behavior.

Also if I run

echo asdf>"${TAP_DIR}"/bogus_file

before

lndinit -v store-secret --batch --overwrite --target=k8s --k8s.namespace="default" --k8s.secret-name="${TAPRPC_SECRETS_NAME}" "${TAP_DIR}"/bogus_file

it does not hang.

This observed behavior is a result of the

set -e

line at the top of the example script. The backgrounded subshell is exiting, not hanging.
