init step logs spills into subsequent step

[wass3rw3rk]

Description

In certain scenarios it is possible for the init step logs to be prepended to a subsequent step's logs erroneously. Using the pipeline below, you will see that the clone step logs will start out with the init step logs' content.

Value

Log should be properly captured in all scenarios.

Useful Information

pipeline to reproduce:

.vela.yml

version: "1"

steps:
  - name: echo
    image: alpine:latest
    commands:
      - echo hello

secrets:
  - origin:
      name: vault one
      image: alpine:latest
      parameters:
        log.level: trace
  - origin:
      name: vault two
      image: alpine:latest
      parameters:
        log.level: trace

Secrets plugin is faked here for ease of testing. This will reproduce the issue 100% of the time in my testing. Check clone step log to see the issue.

A scenario we have seen this in is when folks use multiple templates and multiple are using the secret plugin.

1. What is the output of vela --version?

<= v0.25.x

2. What operating system is being used?

3. Any other important details?

this is a dupe of #985, but inclined to keep this one open due to additional info - otherwise we can move the info to the other issue.
