Fix for error when used with recent vite and vinxi

[kshepherd2013]

I include the complete fix, and can create a pull request if you wish.
The change is to simply add safety checking on two input parameters.

I attempted to upgrade our use of vite-plugin-solid to v2.7.11, along with an upgrade of vinxi to v0.5.8 and also vite to v5.4.19 in a cloudflare wrangler solidjs environment.
Versions not working (I also see the same lines in the latest src):
vinxi@0.5.8
vite-plugin-solid@2.11.7
vite@5.4.19
wrangler@4.22.0
solid-js@1.9.7
@solidjs/start@1.1.5
@solid-primitives/storage@4.3.3
@solidjs/meta@0.29.4
@solidjs/router@0.15.3

Versions which DO work:
vinxi@0.4.3
vite-plugin-solid@2.10.2
vite@5.4.11
wrangler@3.96.0
solid-js@1.9.3
@solidjs/start@1.0.10
@solid-primitives/storage@4.2.1
@solidjs/meta@0.29.4
@solidjs/router@0.15.1

We get a build breaking error of:
TypeError: config.resolve.conditions is not iterable
This is completely fixed by changing lines 293 and 295 of vite-plugin-solid/src/index.ts
from:
293: config.resolve.conditions = [...defaultClientConditions];
295: config.resolve.conditions = [...defaultServerConditions];
to:
293: config.resolve.conditions = defaultClientConditions?[...defaultClientConditions]:[];
295: config.resolve.conditions = defaultServerConditions?[...defaultServerConditions]:[];

Here is the complete build log:
