Regression in 0.5.0 using trim_blocks

[visr]

Hi, thanks for this package!

This example started failing with MethodError: no method matching lstrip(::Nothing). If I disable trim_blocks it works fine. If I use autospace, it crashes with the same error.

tmp = Template(
    """
{% for i in 1:3 %}
    Hello {{ i }}
{% end %}
""";
    path = false,
    config = Dict("trim_blocks" => true),
)
tmp()

The full stacktrace, on Julia 1.10 and OteraEngine 0.5.0:

ERROR: TemplateError: failed to render: following error occurred during rendering:

Closest candidates are:

Thanks for your report. It was ridiculous mistake. This bug was fixed and released as v0.5.1.
